The concept of secondary depression and its relationship to comorbidity.
The data suggest that the primary/secondary concept is more appropriate than the concept of comorbidity. This is based on the fact that many psychiatric illnesses have very high frequencies of depression associated with them, far more than what would be considered expected by chance. The secondary concept is important in that it has considerable clinical meaning and is a way to predict response to treatment and course after the patient is seen by a clinician.
